The Costa Book Awards are a series of literary awards given to books by authors based in the United Kingdom and Ireland. They were known as the Whitbread Book Awards until 2005, after which Costa Coffee, a subsidiary of Whitbread, took over sponsorship.
The awards, launched in 1971, are given both for high literary merit but also for works that are enjoyable reading and whose aim is to convey the enjoyment of reading to the widest possible audience. As such, they are a more populist literary prize than the Booker Prize.
